Description

Remote Controlled Mass Sample Point Source Irradiation Rack and Irradiation Laboratory

technical field

The invention belongs to the technical field of experimental equipment, and in particular relates to a remote-controlled large-volume sample point source irradiation rack and an irradiation laboratory comprising the same.

Background technique

The role of ionizing radiation in human production and life has become more and more obvious. As a double-edged sword, its potential harm to people has also received more and more attention. Radiobiology research is the basis for promoting radiation protection, and its research results have important theoretical significance and application value in the formulation of radiation protection limits and the evaluation of radiation protection effects. In this type of research, the radiobiological effects are closely related to the radiation type, location, dose, dose rate and surrounding material environment of the irradiation model. In the specific experimental process, cell lines, nematodes and experimental animals are often selected as research objects.

Neutrons play a central role in a variety of nuclear facilities, including reactors. And because it is not charged, it has high penetrability, and it is easy to trigger various secondary nuclear reactions, generate charged particles, and form recoil ions, thereby causing serious biological damage effects. Therefore, the impact of neutron radiation on human health has received more and more attention, and research on neutron radiation protection has always been an important topic in the industry. However, there are relatively few studies on the effects and mechanisms of neutron radiation worldwide. The main reasons are: First, neutron sources that can generate sufficient flux are scarce, and neutron radiation fields are precious. In order to make full use of the radiation field space and ensure that each treatment group reaches the predetermined dose, in the previous neutron animal and cell radiation experiments, it was necessary to perform distance measurement and sample placement at least 1 hour in advance; due to too many samples, and The measurement accuracy is limited, and it is difficult to achieve consistent irradiation doses for each batch of samples. Second, due to the influence of residual rays of induced radioactivity, materials cannot be obtained immediately after radiation for short-term experimental exploration. In high-energy neutron radiation experiments, high-energy neutrons ionize air, the ground, and materials in the field, which will cause induced radioactivity. "It is necessary to ensure that the site reaches the dose rate level that allows access, which severely limits the key research on biological effects and mechanisms in the short-term after control.

How to irradiate a large number of samples with accurate and sufficient doses in the process of neutron animal and cell radiation experiments, and realize that the samples can quickly leave the radiation source after irradiation, is the biological effect of neutron radiation and biological protection experiments. Problems to be solved.

SUMMARY OF THE INVENTION

Therefore, in the existing ionizing radiation experiment process, the measurement accuracy of animals, cells and other samples is not high, and it is impossible to achieve accurate dose irradiation of large-scale samples. The purpose of the present invention is to provide a remote-controlled large-scale The sample point source irradiation rack, the remote-controlled mass sample point source irradiation rack of the present invention can realize the spatial positioning and discharge of batch samples, and can obtain accurate dose irradiation; it can also quickly leave the radiation source by remote control after the sample is irradiated , which can prevent the experimenter from entering the radiation field.

The design principle of the remote-controlled mass sample point source irradiation rack of the present invention is as follows:

In the radiation field, the equivalent dose H received by an organism can be approximately calculated as follows:

H=X t

From this, it can be seen that the total dose can be calculated by determining the irradiation dose rate X. However, the X of a point in the radiation field of the point source decreases with the increase of the straight-line distance from the radiation source, and satisfies the following inverse square relationship:

X=Γ·A/L ²

where A is the radioactivity of the source, Γ is the exposure rate constant, and L is the straight-line distance from the point source.

Thus, in an irradiation event with known point source irradiation parameters, if L is measured, H can be calculated.

In the present invention, each of the fan-shaped support surfaces is arranged with a coaxial center line. When in use, each of the fan-shaped support surfaces can place multiple samples along each of the circular arc marks from the inside to the outside, and then the remote control The point source irradiation rack for large batches of samples is moved to the irradiation position, and the point source of radiation (including but not limited to ionizing radiation sources such as neutron point sources, cobalt ⁶⁰ photon point sources, etc.) is at the axis line, and the sample is up and down. The radiation point source is surrounded by multiple layers at the front and back, and the neutron irradiation is received at multiple layers, which greatly improves the utilization rate of neutrons, can maximize the use of the precious space of the radiation field, and save the time for placing and withdrawing samples. And each point on the same arc line marking scale on each of the fan-shaped support surfaces has the same distance from the radiation point source, so it has the same irradiation dose per unit time, then the radiation point source and the remote-controlled mass sample point source radiate When the height of the photo frame remains unchanged, the irradiation dose per unit time on the arc marking scale will remain unchanged. According to the above principle, the actual length of each arc marking scale from the point source can be accurately calculated and marked, so as to accurately Calculate the irradiation dose per unit time and the total irradiation dose.

In order to facilitate the positioning of the remote-controlled mass sample point source irradiation rack, the radiation point source is located at the axis of the several fan-shaped support surfaces.

Preferably, each of the fan-shaped support surfaces is arranged at equal intervals up and down. When the height of the radiation point source is in the middle position, the several fan-shaped support surfaces are symmetrical up and down, so there will be arc marks with the same irradiation dose up and down. When the sample volume is large, it can be placed up and down to precisely control the irradiation dose. accuracy and uniformity.

The design principle of the remote-controlled mass sample point source irradiation rack of the present invention is as follows:

In the radiation field, the equivalent dose H received by an organism can be approximately calculated as follows:

H=X t

From this, it can be seen that the total dose can be calculated by determining the irradiation dose rate X. However, the X of a point in the radiation field of the point source decreases with the increase of the straight-line distance from the radiation source, and satisfies the following inverse square relationship:

When the height of the photo frame 1 remains unchanged, the irradiation dose per unit time on the arc marking scale 111 remains unchanged. According to the above principle, the actual length of each arc marking scale 111 from the point source can be accurately calculated and marked, and then it can be accurately calculated.
